Chaos Surge

You summon a surge of chaos magic from the plane of Limbo to assail one foe you can see within range. 

Firstly, roll 1d6. The target must make a saving throw depending on what number you rolled, as shown below:

On a failed save, a target takes 1d6, 1d8, 1d10 and 1d12 damage, or half as much on a success. The damage type is determined by the number rolled on the d10, as shown below:

If the creature fails the saving throw and at least two of the damage dice roll the maximum or minimum amount of damage possible, the surge of energy then jumps to another target within 30ft of the first one. If this happens, you must reroll the d6 and they must make the saving throw and roll damage as normal, potentially causing the surge to leap again. The surge cannot target the same creature twice during the same turn.

at higher levels: if you cast this spell with a spell slot of 3rd level or above, it deals extra damage, as shown below:

• 3rd level: 1d6
• 4th level: 1d6+1d8
• 5th level: 1d6+1d8+1d10
• 6th level: 1d6+1d8+1d10+1d12
• 7th level: 1d6+1d8+1d10+1d12+1d6
• 8th level: 1d6+1d8+1d10+1d12+1d6+1d8
• 9th level: 1d6+1d8+1d10+1d12+1d6+1d8+1d10

If you cast this spell with a 5th level or higher spell slot, you can choose which of the d10s determines its damage type.
